ODYSSEY INFRARED IMAGING SYSTEM ACCURATE QUANTIFICATION MULTIPLEX DETECTION HIGH SENSITIVITY DIRECT DETECTION CLEAR DATA WIDE RANGE OF APPLICATIONS ® ODYSSEY ® INFRARED IMAGING SYSTEM Infrared Fluorescence Upgrade to Quantitative Westerns Direct infrared fluorescence detection on the Odyssey Infrared Imaging System provides the established standard for Western blot analysis that can’t be equaled with chemiluminescence and visible fluorescence. Infrared detection gives you the quantitative analysis and wide linear dynamic range that chemiluminescence cannot. Strong and weak bands on the same blot are accurately detected without the uncertainty and inconvenience of multiple exposures, and without spending time in the darkroom. The Odyssey System gives you clear, sharp, reproducible bands without fuzziness or “blowout”. Bands hidden by overexposure with chemiluminescence are clear in Odyssey images.

The Odyssey System, using infrared fluorescence detection, reproducibly detected 1.2 pg of Tf, while only 4.9 - 9.8 pg was detected with chemiluminescence. Infrared detection sensitivity was approximately 200-fold greater than previous studies with visible fluorophores (Cy®3, Cy®5, or FITC). The Odyssey System provides a flexible, multifunctional This high background limits the sensitivity of visible fluores- platform to accommodate a variety of applications, so you cent systems and makes it nearly impossible to detect low- get results faster. One example is the In-Cell Western™ abundance proteins at endogenous levels. At the infrared assay, an immunocytochemical technique performed with wavelengths detected by Odyssey, both autofluorescence cultured cells in microtiter plates. This assay uses target- and light scatter are dramatically reduced. The result is specific antibodies to quantify protein levels in fixed cells. the cleanest background, highest signal-to-noise ratios, Accuracy, reproducibility, and throughput are all increased and best detection sensitivity available with a fluorescent by eliminating time-consuming, error prone steps such as system. lysate preparation and gel electrophoresis. Cy3 (550 nm) Cy5 (649 nm) The Infrared Advantage LI-COR IRDye® 680LT (680 nm) LI-COR IRDye® 800CW (780 nm) In the visible wavelength range used by most fluorescent imaging systems, membranes and plastics produce high background due to light scattering and autofluorescence.

Dilutions of mouse antibody were spotted as antigen, and detected with HRP- or IRDye infrared dye-labeled goat anti-mouse antibodies. Chemiluminescent data were collected using ECL substrate and a CCD camera with varying exposures; the infrared image was obtained in a single scan with the Odyssey System. For a 30 minute chemiluminescent exposure, the data set was linear over a 250-fold range. In contrast, infrared detection displayed a quantitative linear range greater than 4000-fold (3.6 orders of magnitude). A paper detailing this study can be downloaded at www.licor.com/chemiccd. Multiplex Western Detection The two infrared fluorescent detection channels of the Odyssey System enable simultaneous two-color target analysis – an advantage that’s not available with chemiluminescent or radioactive methods. Two-color Western analysis makes normalization easy and eliminates error introduced by stripping and reprobing or by comparison of separate blots. Superior image clarity and detail make it easier to detect subtle mobility shifts caused by protein modifications such as phosphorylation. Mean Membrane Signal Infrared vs. Visible Wavelength Membrane Background Fluorescence Nitrocellulose and PVDF membranes were scanned on the Odyssey Infrared Imaging System at an Intensity = 5 for both 700 and 800 nm wavelengths. The same membranes were scanned at a 532 nm and 635 nm wavelength with a PMT=500 on a GenePix® 4100A (Molecular Devices). 3000000 25000000 2000000 1500000 1000000 500000 0 532nm 635nm 700nm 800nm Wavelength Unstimulated Stimulated 1.

Two fold serial dilutions of lysate are shown. Total ERK (Cy5) c) 532 nm Image Phospho-ERK (Cy3) A. Odyssey Near-Infrared Images: The single-color images (1b & 1c) were collected simultaneously. Images were overlaid (1a) to show both total ERK and phospho-ERK (yellow color indicates overlap of red and green signals). The mobility shift caused by phosphorylation can be seen in the EGF-stimulated lysate. B. Visible Fluorescence Images: 532 nm and 633 nm images were collected separately. High background obscures visual observation of phospho-ERK and the mobility shift in the EGF-stimulated lysate. Accurate Quantification 3 ng Through the innovative use of infrared fluorescent labeled antibodies rather than enzyme labels, the Odyssey System provides a broad, linear dynamic range to accurately detect strong and weak bands on the same Western blot. 0.37 pg Two-fold serial dilutions of labeled antibody (6 ng to 0.19 pg) were spotted on nitrocellulose and imaged in the 700 nm channel. R2=0.998 pg Protein 10000 In contrast, the dynamic enzymatic nature of chemiluminescence allows you to capture only a “snapshot” of the enzymatic reaction and is highly dependent on timing and exposure, limiting linear range and offering only qualitative or semi-quantitative results. The accuracy and linearity of the Odyssey System detection allows you to be confident 1000 about differences you see in protein levels, and your blots 100 can be archived and imaged again months later, if needed. 10 1 0.1 10 100 1000 10000 100000 1000000 Integrated Intensity B D Two Independent Infrared Detection Channels D C A E A 700 nm Channel Image F Two separate lasers and detectors simultaneously detect both fluorescent signals. The optical system employs diode lasers and solid-state detectors due to their long lifetimes and very low maintenance requirements. Infrared laser excitation outperforms systems that use white light and filter wheels by delivering higher intensity excitation light to the fluorophore. A variety of fluorescent dyes and stains are compatible with the 685 and 785 nm excitation wavelengths of the Odyssey System’s two diode lasers. Spectral overlap is minimized by the 100 nm separation of the two detection channels, and optical filtering assures that each detector measures fluorescence from only one of the infrared dyes. 800 nm Channel Image G 25 µg 2.5 µg Overlaid Images Beams from solid-state 685 and 785 nm lasers (A) are focused to form an excitation spot on the scanning surface. A microscope objective (B), focused on the excitation spot, collects light from both fluorescing infrared dyes. Light from the microscope objective is passed through a dichroic mirror (C) that splits the light into two fluorescent signals. The fluorescent signals travel through two independent optical paths and are focused on separate silicon avalanche photodiodes (D) and detected. In this example, 700 nm fluorescence (IkappaB) is shown in red (E) and 800 nm fluorescence (Tubulin) is shown in green (F). The two colors were imaged simultaneously in a single scan and can be displayed separately or together in a single image (G). * Data courtesy of Dr. Catrin Albrecht, IUF, Germany EMSA/GEL SHIFT ASSAYS IN-CELL WESTERN ASSAYS COOMASSIE-STAINED GELS DNA GEL STAINING PROTEIN ARRAYS TISSUE SECTION IMAGING Data courtesy C. Kearns, University of Washington In-Cell Western™ Assay For Ratiometric Protein Analysis The In-Cell Western is an immunocytochemical assay performed in microplate format. Target-specific primary antibodies and infrared-labeled secondary antibodies are used to detect target proteins in fixed cells, and fluorescent signal from each well is quantified. Accuracy is enhanced and data are more meaningful because proteins are detected in their cellular context.
